“Continental-scale temperature variability during the past two millennia”; Nature Geoscience
Global average temperatures were the hottest in 1400 years in the 20th century, more specifically during the period 1971-2000, according to a first-of-its-kind scientific study. The study, conducted by a team of 78 climate researchers in 24 countries, helps break new ground in climate science in that the team compiled direct and proxy data from a range of sources to reconstruct 2000 years of temperature change for seven continental-scale regions. The global warming trend they detected, which began in the late 19th and accelerated over the course of the 20th century, is in stark contrast to, and reverses, a long-term cooling trend that lasted well over 1000 years.
Reconstructing climate change across seven continental-scale regions over the past 2000 years, the researchers drew on direct observations of temperature, as well as a variety of proxy data that included ice and coral reef cores, tree-ring measurements, pollen and lake sediment sampling. The study, “Continental-scale temperature variability during the past two millennia,” was published in the current issue of Nature Geoscience. Read More→

Solar photovoltaic (PV) power generation has garnered the most attention from project developers, large business groups and investors in Japan in the wake of the 2011 tsunami and nuclear power plant disaster and introduction of a 
The key facilitator in multilateral, international efforts to halt deforestation, forest degradation and resulting greenhouse gas emissions, the Forest Carbon Partnership Facility (FCPF) recently announced some $23 million in new grant funding for six additional REDD+ Country Participants.
The cross-cutting and mutually reinforcing social and environmental benefits of assuring equitable access to safe, clean, sustainable supplies of water have long been recognized as central to building and maintaining healthy societies and assuring environmental health and integrity. In a warming world experiencing ever-increasing greenhouse gas emissions and environmental degradation, water security has taken on even greater importance.
